SPEOIFIGATIO K forming part of Letters Patent No. 258,923, dated June 6,1882.

Application filed January 27, 1382. (No model.)

To all whom it may concern:

Be it known that I. FRANK A. V'HOLLIEN- BECK, of Syracuse,in the countyof Onondaga,

in the State of New York, have invented new and useful Improvements inBreech-Loading Fire-Arms, of which the following, taken in. connectionwith the accompanying drawings; is a fnll, cle ar, and exactdescription.

, This invention relates to certain novel devices for operating atliree-barreled gun by only two locks and hammers,- and also hasreference to various improvements in the construction of breechdoadingguns generally, and

in the mechanisms essential to the successful operation of the same.

" The invention is fully illustrated in the an nexeddrawings, whereinFigure 1 is a longi-,

tudinal section of my improved"breech-loath, p g fire-arm. theforwardpos tiQlL of id sectlon being taken along the side of the usuallug on the under side of thebarrls, the rear part of the section beingtaken on the line parallel with the shifting-bar, which bringsthetiring-pin, of thethird barrel into operation with the hammer of thegun. Fig. 2is a side view, showing the barrels in a tilted position.

Fig. 3 is a transverse section on line mm. Fig..

i 4 is a face view of the breech of the barrels.

Fig. 5 is adetached top view of the breech block or frame. Fig.6 is aview of the under:

of the barrels on line y y. Figs. 8 and 9 are enlarged detail views ofthe sight audits don nection with the gun, and Fig. 10 illustratesmodifications in the construction and arrangement of the shifting bar. 7Similar letters of reference: indicate correspending parts.

care placed in their operativeposition on the breech-block or frame, asshown in Fig. 1 of the drawings. By the engagement of the for ward faceof the lug 1 with the rear face of a bridge, L, on the breech-extensionbetween the two recesses or mortises I and l the recoil of the gun, whenfired, is counteracted and the hinge-pin F relieved :of the strainincident to the tendency of the separation. of the barrels is hinged alink, p, the free end of which has its cross-bar passing through aninclined slot, o,in the forward lug, i. The sloto is extended throughthe rear end of said lng,'and ter ninates with a notch, 0', in the upperface of the lower portion of the slotted lug, as best seen in Fig. l ofthe drawings. [In tilting the barrels, as shown in Fig. 2 of thedrawings, the free end of the link is drawn toward the rear end of theslot 0 and drops into the notch .95". th rebl arresting cthetmovemeutwofthe of the resultant strain.

Erepresents the extractor ,rel 0, said extractor having a forward-e.tended tongue, is, which slides in alongitudinal groove or channel, 7:,in the lugs 'i i, and

end against the cross-bar-of the free end of the link p when saidextractor is in its dormant position and the barrels brought down upon'the breech-block or frame. The extractor is secured in the groove It byan extra plate, L W'l ich' is removably attached to the bottom oftlielug i, so as .to facilitate the"const ruc-. tion arid repairs of thegroove constituting the guide for the extractor the said extractor isprovided with a longi tndiual slot, m, through which passes a screw or.pin,' n, said pin, serving to prevent the extractor from slidingoutendwise and becoming lost when slot m is of such a length as to allowthe ex tractor E-to carry the for said lug whenever it is desired to thebarrels from the stock.

ed to engage'the primed and of the cartridge.

from the stock. To the sides of the bridge L 19' barrels and-relievingthe hinge of the barrels is of sufficient length torest with its forwardinserted transversely in thelug i;

the barrels are detached from the stock. The 4 be pushedrearwardsnfiicient to ward end of the tongue k out of the log t, andthus allow the free end ofthe link p-to he swung out of its engagementwith disconnect D represents the extractor'for the shotgun-rep barrels BB, it consisting of a plate, It, adaptor shell, and having aforwardlyextended stem sliding in a channel in the metal between the twobarrels B B. The extractor D is operated by the extractor E, which has ashoulder, 9, engaging the rearof the plate h of the extractor D, andthus forces the same rearward or outward simultaneously with therearward movement of the extractor E.-

a and aare the firing-pins for the respective barrels. Said firing-pinsmovejn bushings t-in therear end of the firing-pin of one of theshotgun-barrels and of the firing-pin of the riflebarrel, saidshifting-bar being provided with two apertures, r 1', arranged in suchrelative positions that while one is in coincidence with its adjacentfiring-pin the otherapertureis normally out of coincidence with itsrespective fir-' ing-pin. The shifting-bar has a lateral as well as asliding movement, and is by means of a spring, 6, held normally in sucha position as to bring the aperture 7" of saidbar in coincidence withthe firing-pin ot' the rifle-barrel, and by means of springs e and apressing against the shifting-bar, respectively at the base and upperportion thereof, said bar is held yieldingly rearward, so as to allowthe two tiring-pins to be repelled back into the recoilplate orbreech-block by the rebound'incident to the firing of the barrels.

Back of the upper end of the shifting-bar s, and in range with thefiring-pin of the shotgun-barrel, is a plunger,-b, provided with anaxial cavity, 0, adapted to receive the rear end of the aforesaidfiring-pin, as hereinafter explained. The aforesaid position of theshiftin g-bars brings the solid portionthereof across the rear end ofthe firing-piuof the shotgunbarrel. Thus when the plunger b is struck.by the hammer H said plunger throws the shifting-bar aforward, and-thelatter in turn propels the firing-pin ot the shotgun-barrel anddischarges said barrel, while the lower aperlure, r, of the bar 8 allowsthe firing-pin ot'the rifle-barrel to pass through said aperture, and

. thus prevent the simultaneous firing ot' the rifle-barrel. The lowerextremity of the shifting-bar s protrudes at the surfaceof the stock,and is provided with a suitable handle, by means of which said bar canbe pushed inward, so as to bring the upper aperture, 1', thereof incoincidence with the firing-pin of the shotgun and the solid portion ofthe bar below the lower aperture, r, across the firing-pin ot' theriflebarrel. A shoulder, d, or other suitable catch on the bar 8,engaging with a shoulder on t e inside of the stock, retains the saidbar in i' s aforesaid position. If thegun is then fired, the" firing-pinof the shotgun-barrel passes through the aperture r of the upper end ofthe shift-' ing-bar and into the cavity 0 of the plunger 1), thusleaving the charge of the shotgun barrel undisturbed, while at the sametime the solid lower portion of the shifting-bar forces the tiring-pinof the rifle'barrel forward, and thus discharges said barreL, Theforward thrust of the shitting-barscauses the shoulderd thereof tobecome disengaged, and so soon as this is etfected the spring 0 forcesthe shifting-bar longitudinally and restores the same to themsition forfiring the shotgun-barrels, as before described.

, In order to render the-tripping of the shiftin g-bar adjustable, so asto change itsposition at the proper time, I apply to the exterior of thestock, and in close proximity to the shiftihg-bar, an eccentric screw orbutton, f, against which the lower extremity of said bar rests. Byturning said screw the rearward thrust ot' the aforesaidportion of theshifting bar can be checked to increase or diminish the engage ment ofthe shoulder d, as may be desired.

The plunger 1) is 'retained in the stock by means of a small screw, it,inserted through the-side of the stock, and engaging with a longitudinalgroove in the sideof-the plunger,

as best shown in Fig. 1 of the drawings.

The' rear end of the barrels is locked on the breech-block or frame bymeans of a'lever, m, pivoted on top of the tang T in the mannerhereinafterexplained, said lever passing with its forward end through alaterally-enlarged channel, which is extended through the solid portionof the breech-block, and thus completely incloses said end of the leverm and efleetually sustains the same to resist the upward strain wheninterlocked with the rear end of the barrels. The described channelallows the lever to swing laterally and engage a notch, N, in arearwardly-extended book, 0,

on the breech of the barrels, said hook enterv ing a cori'espondingmortise in the upper part of the breech-block. The lever M, I providewith an "eye, by which I pivot it on a cylindrical projection or boss,1, on top of thetang T and integral therewith, in the center of whichboss is a hole, 2, extending vertically through the tang. In this hole Iinsert the stem 3, which .carries thesight 4, saidstem being providedwith a vertical slot, 5, through which passes a pin, 6, inserted throughthe side of the tang. Between the rear side of the stem 3 and the.

adjacent side of the hole 2, I place a spring, 7,

which by frictional hold on the saidstem retains the sight in itsdesired position. The upper end of the spring 7 is extended over the topof the boss 1 and over a portion of the lever M, and thus forms a key tohold the latter down upon the tang. 1

and in conjunction with the bearing of the lug t" against the hinge-pinF completes the connection of the barrels with the breech-extension.Heretofore the fore-end and tip-strap were'firtnl y united and operatedas ifformed in one piece.

. Consequently it was exceedingly diflicult to render the sameadjustable so as to compensate for the wear of the bearing of the tip-strap on the end of the breech -extension,.although it has beenattempted to accomplish the said object by means of a spring pivoted onthe combinedlipmtrapandfiireemi, and bearin g with its free end on a lugon the under side of the barrels, yet the construction and arrangementof the spring were such that a slight wear and secured thereto by a.screw or screws passing through said parts.---

In the beveled end of the tipstra-p there isg S, in which is placed a spring, U, in the form of a bow, which has itsrearend hooked onto a book, 8, in the rear end of the mortise.

Thefonward end of the springs projects into a mortise in the shank R andin the fore-end, and is formed with arearwardly-inclined or reversedcurved face, V, which bears on a stud, 9, or other suitable shoulder intheinortise of the shank It, and thereby crowds the tip-strap upwardagainst the said shank and rearward against the end of thebreech-extension, and by the latter action causes the tipthe lost motionincidentto of the breech-extension. The free end of the spring Uterminates with a rearward extension, 10, which passes underneath across-pin,

.11, in the tnortisd of the tip-strap, and thus retains said spring, inthe mortise. The spring U has suflicient elasticity to allow the forwardend of the tip-strap to be pulled out by applyfinger in a recess, 12,,and the un'der side of the tip strap; The upper end of-the shank It andthe asegmental face, 14, which is concentric with the hinge ot' thebarrels, and at thesaid face-there are two set-screws, 15, in- Q."

One of the modifications of theconstruction and arrangement of the shifting-bar is illustrated in Fig.10 of the drawings, and consists in terminating said shifting-bar insideof the breech-block and connecting thereto a pivotal lever, 16,which-projects through the side of the breech-block. By depressing theouter end of said lever the shifting-bar is moved upward to bringthe-solid lower portion thereof nverthe'flriifg piiibt' marine-barrel,and simultaneously bring the aperture in the upper end of said bar incoincidence with the firing-pin of the shotgun-barrel. A reversemovement of the lever 16 restores the shifting-bar into rifle-barrel andfor firing the shotgun-barrel.
